Switch and multiplexer shrink for
portable use
A new analogue switch and multiplexer packaged in the 3 x 3mm QFN-12 package are aimed at battery-operated portable applications.
A new analogue switch and multiplexer packaged in the 3 x 3mm QFN-12 package are aimed at battery-operated portable applications The new DG2032 dual SPDT analogue switch and DG2034 4:1 multiplexer are the first products in the QFN-12 to combine low 3ohm on-resistance, low power consumption, and superior switch performance while operating over a wide power supply and analogue signal range of 1.8 to 5.5V

Drivers integrate MOSFETs with drive circuitry
Five new Little Foot Plus driver products are designed to simplify the use of N-channel MOSFETs in high-frequency buck regulators.
Unlike other small analogue switches aimed at audio only, these parts cater to the needs of both audio and higher-speed analogue signal switching for port sharing/extension, data acquisition, PC Cards (PCMCIA), audio/video signal routing, speaker/headset switching, and similar applications in end products such as cellphones, digital cameras, PDAs, MP3 players and handheld test and healthcare equipment.
While retaining the desired switch performance at very low power consumption, these devices boast high switching speeds and outstanding linearity over the full supply and signal voltage range.
The DG2032 dual SPDT analogue switch features a low on-resistance specification of 3ohm at 2.7V, with wide dynamic performance better than -80dB for both crosstalk and off-isolation at 1MHz.
With its fast switching speeds (25ns turn-on, 13ns turn-off), low on-resistance, high bandwidth and low charge injection, the DG2032 is well suited for switching a wide range of audio and video signals.
The DG2034 4:1 analogue multiplexer offers low on-resistance of 4ohm and off-isolation and crosstalk of -55dB at 10MHz.
The turn-on time is fast at 25ns.
In addition to the QFN-12, the DG2034 is also available in the MSOP-10 package.
Providing good value for cost-sensitive applications, the new products are the latest in a growing family of low-voltage, high-density CMOS analogue switching devices from Vishay Siliconix that give designers a wider choice of surface-mount analogue switching options for battery-powered, portable designs.
Samples and production quantities of the DG2032 and DG2034 are available now with lead times of six to eight weeks for larger orders.
Pricing for US delivery in 10,000-piece quantities is $0.60 for the DG2032 and $0.70 for the DG2034.
